NON-INFLAM'MABLE LUBRICATING-OIL.

No Drawing.

To all whom it may concern.-

Be it known that I, Jonas W. Am

won'rn, a citizen of the United States, and a bei resident of East Orange, in the county of Essex and State of New Jersey, have invented a certain new and useful Non-In-. flammable. Lubricating-Oil, of which the following is a description.

My invention relates to a lubricating agent which has the physical proper? of non-inflammable or diflicultly In a Inab e imparted to it, whereby the danger from fire in situations in which such lubriare the various chlorin substitution products of napthalene, with the exception of the hepta and per chloro naphthalene. Other halogen substitution products of carbocyclic compounds which are of waxy or greasy texture, however, may be used with equally good results, but the greater cost of such products renders their use less desirable. The halogenized substitution products which I find best suited for the purpose have the halogen so firmly combined in the ring or closed chain of the compound that they are very stable-and have no corrosive action on metals at temperatures considerably higher than that of boiling water.

The particular halogen which I find best suited for the purpose ischlorin, both on account of its low cost and the stability of its'substitution products of the class herein described. The desired chlorin substitution products are produced by subjecting the 'carbocyclic compound, preferably naphthalene, to the action of chlorin gas while the compound is heated and under pressure until the desired degree of chlorination is attained, treatingthe product with an alkali, and distilling the product. The product may be further purified from traces of hy- Machinery oil 100 d ochloric acid which are -formed during d stillation by treating the same with finely divided oxid or carbonate of lead and filtering, or by boiling; or washing with dilute alkali and washing with hot water.

The product, which may be any of the chloronaphthalenes below the hepta is dissolved in the hot oil or grease to which it is desired to impart the roperty of being non-inflammable or difiicu tly so.

Specification of ma ma,- P tented June 11, 1912. Application filed 0mm 14, 1910. sum no. 502,044. I

Examples of compositions of the char acter described are parts.

Tetra-chloro-naphthalene Q20 to 60 parts. Mono-chlore-naphthalene- 20 to 60 parts.

This compound forms a medium ma chinery Oll.

Heavy cylinder oil "100 parts. Tetra-chloro-naphthalene 50 to 100 parts. Mono-chloro-naphthalene -50 to 100 parts.

This forms an oil for heavy machinery.

Mono-chloro-naphthalene i parts. Light parafiin o1l 20 to 50 parts. Tetraor tri-chloro-naphtha- I lene -20 to 50 parts.

This forms a light machinery oil.

Heavy mineral oil 50 parts.

Tetra-chloro-naphthalene -50 to 100 parts. L quid chloro-naphthalene-.10 to 35 parts.

The last cited mixture is made hot, whereby a perfect solution of the ingredients takes place. The mixture is allowed to cool and 'part' of the chloro-naphthalene crystallizes out as soft waxy crystals which are mashed up into'a uniform paste in asuit-able mill. This composition forms a grease suitable for very heavy machinery and car axles.

(5.) For a non-Mid oil.

Tetrahloro-nap tha1ene 5() parts.

Calcium stearate 5 to 10 parts.

heavy. mineral oil are trade terms employed to designate light, medium and heavy hydrocarbon lubricating oils respectively.

Having now described my invention, what I claim and desire to protect by Letters Patent is as follows 1. As a new composition of matter, a lubricant'com rising a lubricating oil having dissolved t erein a halogen substitution product of a carboc clic compound in which the halogen is in t e ring or closed chain, substantially as described.

2. As a new composition of matter, alubricant comprising a lubricating oil having dissolved therein a chlorin substitution product of acarbocyclic compound in which the chlorin is in the ring or closed chain, substantially as described. v

3. As a new composition of matter, a lubricant com rising a lubricating oil having dissolved t erein a halogen substitution product of a carbocyclic compound having lubricating properties, substantially- .as de scribed.

4. As a new composition of matter, a lubricant comprising a lubricating oil having dissolved therein a chlorin substitution product of a carbocyclic compound having lubricating properties, substantially as described.

5. As a new composition of matter, a lubricant comprising a lubricating oil having dissolved therein a halogen substitution product of a carbocyclic compound of waxy texture, substantially as described.

6. As a new composition of matter, a lubricant comprising a lubricating oil having dissolved therein a chlorin substitution product of a carbocyclic compound of waxy texture, substantially as described.

7. As a new composition of matter, a lubricant com rising a lubricating oil having dissolved t erein a halogen substitution product of a carbocyclic compound which is non-corrosive to metals, substantially as described.

8; As a new composition of matter, a lubricant comprising a lubricating oil having dissolved therein a chlorin substitution product of a carbocyclic compound which is non-corrosive to metals, substantially as described.

9. As a new composition of matter, a lubricating oil having a halogen substitution product of naphthalene dissolved therein, substantially as described;

10.As a new composition of matter, a lubricating. oil having a chlorin substitution product of naphthalene dissolved therein, substantially as described.

11. As a new composition of matter, a lubricating oil having a chlorin substitution roduct of naphthalene, of a degree of chlorination lower than hepta-chloro-naphthalene, dissolved therein, substantially as described.

12. As a new composition of matter, a composition comprising lubricating oil and tetraand mono-chloro-naphthalene, substantially as described.

This specification signed and witnessed this 8th day of October 1910.
